Why STREAM

GIGABYTES OF DATA.
ZERO WAITING.

Navigate Massive Terrain Without Lag

When you open DEMs and orthophotos that are hundreds of megabytes — even gigabytes — the program never stalls. Only the area you're looking at loads in full detail.

Prepare Once, Always Open Fast

On first load STREAM converts your data to its own fast format. The next time you open the same data, it appears on screen within seconds.

All Your Field Data in One Place

View DEMs, orthophotos, point clouds and CAD drawings overlaid in the same scene — together with their coordinate system.

Automatic Terrain Model from Point Clouds

When you load a LAS/LAZ file, STREAM builds a clean terrain model from ground points, a surface model from all points, or an orthophoto.

Fully Offline, Fully Yours

Your data never goes to the cloud and needs no internet. Everything runs on your computer. Your sensitive project data stays safe.

Multilingual, Two Themes

Turkish, English, Spanish, French, Chinese and Russian interface. Light/dark theme and one-click metric/imperial unit switching.

Measure Stockpiles Instantly

Compute the volume and tonnage of material piles using a reference plane and material density; get a print-ready PDF report for mining, quarry and earthworks.

Compare Two Terrains Side by Side

With multi-screen (Split View) mode, view two terrain scenarios at once with a synchronized camera. Compare before/after or design/existing at a glance.

Tools

THE RIGHT TOOL FOR EVERY JOB

Distance Measurement

Real-world distance between two or more points

Elevation / Height Difference

Read the elevation difference between any two points instantly

Area Measurement

Surface area of closed regions, with instant on-screen results

Volume Calculation

Cut and fill quantities — against real terrain, a flat level or a comparative reference

Stockpile

Volume and tonnage of material piles — with reference plane and material type, PDF report

Terrain Analysis

MAKE SENSE
OF THE TERRAIN

STREAM doesn't just show the terrain — it makes sense of it. View analysis results as a live color layer over the terrain, and save them as raster or vector whenever you want.

  • Slope, aspect and viewshed in one interface
  • Hydrogeology and drainage analyses
  • Customizable contour intervals
  • Profile / cross-section lines
Slope Analysis
Visualize surface steepness with a color scale
Aspect Analysis
See which direction slopes are facing
Viewshed
Visible and hidden areas from a selected point
Line of Sight
Is there an obstacle between two points? Check instantly
Hydrogeology
Water flow and drainage analyses, watershed calculations
Contour Generation
Automatic contour lines at your chosen interval, saved as vectors
Hillshade
Emphasize relief with shaded terrain based on the sun's position
Sun & Shadow Analysis
Sunlight hours and shadow distribution by year and month — for solar panel, agriculture and landscape planning
Change Detection
Compare two terrain scenarios; see cut, fill and elevation changes as a color map

Supported Formats

WHATEVER THE FORMAT

GeoTIFF

Elevation Model & Orthophoto

LAS / LAZ

Point Cloud

DEM

Digital Elevation Model

Automatic Conversion from Point Clouds

When you load a LAS/LAZ file, STREAM offers you choices: a clean terrain model from ground points only, a surface model from all points, or an orthophoto if color is present. A raw point cloud turns into real terrain you can work on.
